Suppose his check was worth $d and c cents, or 100d+c (d,c < 100).He was given 100c+d, and after the newspaper had (100c+d-5)=2(100d+c)
We can't divide through mods but we can multiply by 33 (same result anyways)
As 0 is less than d is less than100, d=31 and it follows that c=63
The check was worth $31.63
Sorry about the double post, for some reason all the text after i typed the 'less than to' sign was cut off. I dunno why that didn't happen with my first one though. Wierd.
